Bouncing Coach

I have a 2010 3400RL with JT Strong Arm Stabilizers installed (3rd coach they have been on) and I can't get this larger coach to stop bouncing when we walk across the floor. I've reset the coach three time since we got to our site in New Braunfels on December 1st. I have also contacted the manufacture, but still bouncing. If any one that has a 3400 and Strong Arms has some ideas, I'm all ears.
Thanks,
Don

Try jackstands just in front of the wheels. Since the coach is supported at both ends and won't rock back and forward, or side to side, because of the JTs, it could be acting like a beam and flexing in the middle.

Don, We have an '06 3400 with the JT's AND, I must say, they take 95% of movement out of the trailer, however, they don't do it all. Remember you are still sitting on air (tires) and I think the stands under the frame as Bob suggests may take it all out. Please post your results. Thanks Phil

I purchased a pair of BAL 7500 pound 24" scissor jacks and installed them just in front of the tires which is half way between the front and rear supports. The bounce you are felling I believe is frame flex over the wheels. With the new suspension it moves a little more.
The scissor jacks have removed the bounce for me.
Yes I have JTs and tire scissor chocks to attempt to stop some of the tire movement in conjunction with the suspension.

We have the JT's on this 06 3400. You must be on a solid surface concrete or black top. We do suplement with jack stands behind rear axle wheels and at the very back of the camper. The camper is solid when we walk around on the inside. We get a vibration when the W/D is on high spin. As Phil states we are still on tires and have a suspension. We will never get all the movement out. 95% is a good figure..
